It seems totally inadequate to say that I am sorry to hear about your health issues but I am, of course.

Without trying to stir controversy, one of the many reasons that I am not religious is that I cannot believe any all powerful deity would find so many ways to inflict such failings of the human body on so many.

I can only wish you the very best during your struggles with all this. Keep your spirits up, my friend,

Light travels faster than sound. This is why some people appear bright until you hear them speak.
